Bjorn Borg and John McEnroe announced on Wednesday that they had committed to lead the Europe and World teams for the first three years of the Rod Laver Cup, a new competition styled after golf’s Ryder Cup.

Tennis legends Roger Federer and Rafael Nadal will join forces for the event, which kicks off in September next year. Teams will be made up of six players each competing in three singles matches and one doubles match per day.

The competition, which will be held annually except for during Summer Olympic years, will rotate between major cities in Europe and the rest of the world.
